There are laboratory tests or scans which can provide a picture of the mineralization of the human body and may assist a person in determining their biological age.

Ferritin is the iron storage protein in the human body.  A ferritin count may help you determine your iron storage level.  In middle-aged adult males and postmenopausal females, a healthy ferritin number would be below 50 and no lower than about 20.

The ferritin number may be skewed by infection or malignancy.  In these states, the human body withholds iron from tissues by binding it to ferritin.  So your iron storage number may be abnormally high during states of infection or when fighting cancer.

A CT scan can be performed to determine if your arteries are hardened by calcium (calcification).  During the CT scan a calcium arterial score (called an Agatston score, name by Dr. Arthur Agatston, South Beach Miami, Florida cardiologist) can be obtained.  If your calcium arterial score is above zero, you have an increased risk for a heart attack.

An elevated blood calcium level only tells you whether your body is excreting excess calcium, like in postmenopause when women are losing calcium from their bones.  Blood calcium levels cannot be used to tell you if your cells or tissues are calcifying.
